解析 21s，(老年人P-R间期>0．22s)如P--R间期正常，心房率与原大致相同或稍快，但P-R间期与以往延长≥0．04s，也可诊断为一度房室传导阻滞。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
